Common Firmware Environment (CFE), sometimes pronounced as 'cafe', [1] is a firmware interface and bootloader developed by Broadcom for 32-bit and 64-bit system-on-a-chip systems. It is intended to be a flexible toolkit of CPU initialization and bootstrap code for use on embedded processors (typically running on MIPS32/64 instruction set CPUs ...
C17, formally ISO/IEC 9899:2018, [1] is an open standard for the C programming language, prepared in 2017 and published in July 2018. It replaced C11 (standard ISO/IEC 9899:2011), [ 2 ] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. [ 3 ]
C11 (previously C1X, formally ISO/IEC 9899:2011), [1] is a past standard for the C programming language. It replaced C99 (standard ISO/IEC 9899:1999) and has been superseded by C17 (standard ISO/IEC 9899:2018).
UEFI requires the firmware and operating system loader (or kernel) to be size-matched; that is, a 64-bit UEFI firmware implementation can load only a 64-bit operating system (OS) boot loader or kernel (unless the CSM-based legacy boot is used) and the same applies to 32-bit.
In this example of dual booting, the user chooses by inserting or removing the DVD from the computer, but it is more common to choose which operating system to boot by selecting from a boot manager menu on the selected device, by using the computer keyboard to select from a BIOS or UEFI Boot Menu, or both; the Boot Menu is typically entered by ...

A Linux boot log showing the usage of TSC as system clocksource. The Time Stamp Counter (TSC) is a 64-bit register present on all x86 processors since the Pentium. It counts the number of CPU cycles since its reset. The instruction RDTSC returns the TSC in EDX:EAX. In x86-64 mode, RDTSC also clears the upper 32 bits of RAX and RDX. Its opcode ...
EasyBCD has a number of bootloader-related features that can be used to repair and configure the bootloader. From the "Manage Bootloader" section of EasyBCD, it is possible to switch between the BOOTMGR bootloader (used since Windows Vista) and the NTLDR bootloader (used by legacy versions of Windows, from Windows NT to Windows XP) in the MBR from within Windows by simply clicking a button.
